Ok, just hooked up everything to my new computer and everything seemed ok, but after i installed the video card drivers and restarted, I got a message saying that my videocard is not getting enough power. I have a Corsair VX 550w power supply. At the moment, I'm running two hard drives. One of from my old computer. I was going to transfer everything from that hard drive over and just use one hard drive. Will that be enough or should i look into another power supply? I have an Antec Nine Hundred Case which comes with 4 fans. I have each fan on medium setting. Also have 2 DVD Drives, one being a burner and the videocard is the XFX 8800GT. Thanks in advance.
